ECL202 inductive measuring system

ECL202 Inductive measuring system (eddy-current)

Top performing system

The ECL202 eddy-current position and displacement measuring system delivers exceptional resolutions, down to 10nm, and bandwidths up to 15kHz. The electronics of the ECL202 are based on the latest FPGA digital technology, delivering excellent noise immunity and very high stability.

The system provides a linear analogue voltage output (0 - 10 Volt) proportional to changes in the target position and a digital (switched) output with a user programmed switching threshold.

 

Key specifications

  • Resolution down to 10 nm (@ 100 Hz)
  • Bandwidth 100Hz, 1kHz, 10kHz, 15kHz (user selectable)
  • Range from 0,25 mm to 15 mm
  • Linearity 0,2%
  • Temp. range: Driver  4-50°C Probe -25°C to +125°C (optional high temp probes)

 

Output features

  • Adjustable offset and set point
  • Analogue output (0-10 VDC)
  • Set point switch contacts
  • Single channel
  • Synchronization kit available (up to 9 systems)

 

Probe choices

Probe model numbers include diamater in mm. The target size must be at least 3 times this probe diameter to maintain specifications. See our probes page for more details. The resolution depends on the selected probe, range and bandwidth. Please contact us for expert advice
